Answer:
42%
Step-by-step explanation:
I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:
(34+8)÷100×100 = 42%

Answer:
1. 523 cm^3
2. 1.6 ft
Step-by-step explanation:
1. Formula for volume of a sphere is (4/3)(pi)(r^3)
r = 5
(4/3)(3.14)(5^3) ≈ 523
2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)
(1/3)(3.14)(1^2)(2) ≈ 2.0933
Plug this into the formula for volume of a sphere and find r.
2.093 = (4/3)(3.14)(r^3)
r ≈ 0.7937
Multiply by 2 to get the diameter, which is the height of the spherical barrier.
r * 2 ≈ 1.6

You are renting a car that charges a $30 fee plus 40 cents a mile. The rate of change is $30.
True or False?
Hi there!
»»————- ★ ————-««
I believe your answer is:
False.
0.40 is the rate of change.
»»————- ★ ————-««
Here’s why:
As mentioned in the scenario, the car company charges a $30 fee which is flat. The '30' is the base for the total cost. The car company also charges 40 cents for every mile driven. This means that the company would charge a 40 cents for a mile driven. 40 cents would be the rate of change, not $30.⸻⸻⸻⸻
Side Note:
An equation that represents the situation could be:
[tex]C = 0.40m + 30[/tex]
'C' is the total cost for renting the car.
'm' is the number of miles the car is driven.
⸻⸻⸻⸻

3.3 + 10m = 7.81 find the value of m ill give brainliest
Answer:
m = .451
Step-by-step explanation:
3.3 + 10m = 7.81
Subtract 3.3 from each side
3.3-3.3 + 10m = 7.81-3.3
10 m =4.51
Divide each side by 10
10m/10 = 4.51/10
m = .451
Answer:
0.451
Step-by-step explanation:
3.3+10m=7.81
10m = 7.81-3.3
10m = 4.51
m = 4.51/10
m = 0.451

Jimmy's truck consumed 2 gallons of gasoline while travelling a distance of 76 km. He has 1.5 gallons left in the tank. How much farther can his truck go?
_______ km
I GIVE BRAINLIEST TO THE FIRST CORRECT ANSWER!!
Answer:
[tex]57\:\mathrm{km}[/tex]
Step-by-step explanation:
Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.
Let [tex]x[/tex] represent how much farther his truck can go, in kilometers:
[tex]\frac{2}{76}=\frac{1.5}{x}[/tex]
Cross-multiplying, we get:
[tex]2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}[/tex]
Answer:
Step-by-step explanation:
2 ÷ 76 = 1.5 ÷ d
2d = 76 × 1.5
d = 57 km

13/16 ÷ N = 2 1/6
What is n?
A:4/9
B: 3/8
C. 4/7
D.5/8
EXPLAIN
Answer:
N = 3/8 (Answer B)
Step-by-step explanation:
Here we need to isolate the variable N. Rewriting 2 1/6 as the equivalent 13/6, we get:
13/16 ÷ N = 2 1/6 = 13/6.
Then 13/16 ÷ N = 13/6, or
(13/16) 13
---------- = ------
N 6
Dividing both sides by 13, we get:
(1/16) 1
---------- = ------
N 6
Cross-multipying results in 6/16 = N.
Reducing this, we obtain the solution, N = 3/8 (Answer B)
Find the dfference between (8a + 2b - 4) and (3b - 5)
Answer:
8a-b+1
Step-by-step explanation:
Difference means subtract
(8a + 2b - 4) - (3b - 5)
Distribute the minus sign
(8a + 2b - 4) - 3b + 5
Combine like terms
8a + 2b-3b - 4 + 5
8a-b+1
